Subsequent reporting by the Los Angeles Times found that the festivities came to life about 10:30 p.m. after a party in nearby Beverly Hills had been shut down by police and revelers, using social media, swarmed an unoccupied Holmby Hills residence.

There were several arrests, including some for pot possession.
